The Cinevate Duzi v3 is a roller bearing slider supporting up to 120 lb loads. It's made of anodized aluminum and features solid 15mm carbon fiber rails providing for both a strong and lightweight system. This version measures 32" in length and will support both small and large cameras.
The Duzi comes with six non-scratch, urethane ball feet which are micro-adjustable in height. Two feet attach on each end-block, and two attach to the slider carriage to provide additional support if you want it. The carriage feet attach slightly off-angle and are suspended; so as soon as you mount a camera the weight will ground the feet for an added measure of stability. If you don't need this extra support you can just keep these feet off.
